PLOW-BEAM.

SPECIFICATION forming part of Letters Patent N 0. 568,457, datedSeptember 29, 1896.

Application filed November 1, 1895. Serial No. 567,660. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRED R. PARISH, a citizen of the United States,residing at Reading, in the county of Schuyler and State of New York,with post-office address at Watkins, in said county and State, haveinvented a new and useful Improvement in Plow-Beams with Joint and LeverAttachments, of which the following is a specification.

This invention relates to certain new and useful improvements inplow-beams, and especially to a beam made up of two sections havingrack-and-pinion adjustment at their adjacent ends, the two sectionsbeing held to metal plates bolted to the sides of the beamsections.

A further aim of my invention resides in the provision of a sectionalplow-beam, one portion of which is pivoted to a plate and adapted to betilted by a rack-and-pinion conneotion, whereby the draft may beregulated.

To these ends the invention consists in the novel construction of parts,as herein de scribed, and illustrated in the accompanying drawings.

I clearly illustrate my invention in the accompanyin g drawings, which,with the letters of reference marked thereon, form a part of thisspecification, and in which drawings similar letters of referenceindicate like parts throughout the several views, in which- Figure 1 isa side elevation of my invention. Fig. 2 is a top plan View. Fig. 3 is avertical longitudinal sectional View, and Fig. 4 is a cross-sectionalView on line 4 4 of Fig. 1.

Reference now being had to the details of the drawings by letter, Adesignates the portion of the plow-beam to which is attached theplowshare and the handles, (not shown,)

and to the sides of this beam are bolted the plates B, having pivoted inapertures therein the shaft 0, to which is keyed the pinion-wheel O, andD is a handle fitted on the square end of the said shaft 0.

Pivoted on a bolt 6, between the ends of the plates 13, is the beamportion E, which has secured to its end adjacent to the pinion a curvedrack-bar G, having arms which are bolted to the section E at F. p

K is a bolt carried by the section E near its longitudinal center andworks in the slot J in the plate B and serves as a guide to allow theportion E to tilt'only a limited distance. The teeth of the said pinionare designed to mesh with the teeth of the curved rack-bar, and bytilting the handle D the beam E may be tilted, as may be desired. A rackM is provided, and a pawl may be pivoted to the handle and adapted torest in the teeth of the rack-bar to hold the beam in a fixed position.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is-

In a sectional plow-beam, the combination with the beam A rigidly boltedbetween the plates B, of the beam E pivotally held between the saidplates and having a guide-bolt K working in slots J in the said plates,of the clevis rack-bar G bolted to the end of the said beam E, of thepinion-wheel O journaled to the plates B and between the ends of thebeams E and A, with suitable handle D and segment M, all substantiallyas shown and described.
